“WE SHOULD RIP BARRON TRUMP FROM HIS MOTHER’S ARMS AND PUT HIM IN A CAGE WITH PEDOPHILES AND SEE IF MOTHER WILL WILL STAND UP AGAINST THE GIANT ASSHOLE SHE IS MARRIED TO. 90 MILLION PEOPLE IN THE STREETS ON THE SAME WEEKEND IN THE COUNTRY. FUCK,” he wrote on Twitter.

Fonda, the “Easy Rider” star and younger brother of actress Jane Fonda, also called for protesters to surround Immigration and Customs Enforcement (ICE) agents while they’re picking up their children from school.

The actor’s tweets came amid national furor regarding the Trump administration’s “zero-tolerance” immigration policy that was enacted earlier this year.

The aggressive measure means thousands of migrant children crossing the U.S.-Mexico border with their parents are being separated during criminal prosecutions.

“Mrs. Trump hates to see children separated from their families and hopes both sides of the aisle can finally come together to achieve successful immigration reform,” Grisham told The Hill on Sunday. “She believes we need to be a country that follows all laws, but also a country that governs with heart.”

All of the living former first ladies — Rosalynn Carter, Laura Bush, Hillary Clinton and Michelle Obama — have spoken out against the Trump administration’s immigration policy.
